Abstract-- Multiple-antennaSAR interferometryinvolves the use of
three or more antennas to reduce the overall phase ambiguities and phase
noise in interferometric data. This paper presents a Bayesian approach to
topographic mapping with multiple-antenna SAR interferometry. Topo-
graphic reconstruction is formulated as a parameter estimation problem
in the model-based Bayesian inference framework. An InSAR simula.
tor based on a forward model is developed for simulating SAR data from
multiple-antenna InSAR for evaluating the Bayesian topographic recon-
struction algorithms. A Bayesian point position algorithm is developed to
estimate the height of a point in the image. A measure of the uncertainty
in estimated position and height is also defined in terms of the spread of
the dominant mode of the posterior distribution. An example demonstrat-
ing the performance of the algorithm for a three-antenna InSAR system
